Trick to loosen O2 sensor?

Even then It still messed the threads up on the way out. It did not matter at that point since the exhaust got junked. I guess if the sensor sits in there long enough it can fuse with the exhaust.The reason I kept mine, was for the new headers. ( I heard the coating can foul up new o2's)
Exhaust rusts over time, and those threads will eventually just rust up completely.
I saw in the rebuilding LT1 book, that they used parafin wax on stubborn bolts. (heat up the part then cover with wax) It is supposed to melt into the threads. I wonder if this is a good thing to try?

If you don't want to try and save the sensor, cut the pigtail off, and use a 6-point box wrench- Like everyone has said, heat is your friend. I have had good luck just letting the engine run for ten minutes, but the next step up would be MAPP gas- similar to propane, but hotter- heat the pipe around the joint, not the sensor
Recommend using AC-Delco for the replacement- I think their tolerances are a little tighter-
